초록
본 연구는 씨름선수들을 대상으로 윙게이트 운동 중 산소기여율의 변화를 바탕으로 보다 낮은 수준의 산소기여율에 의한 무산소성 운동수행능력 평가를 위하여 12명의 대학 씨름선수를 대상으로 30초 윙게이트 검사 중 5초 단위로 대상자들의 산소기여율 변화 및 무산소성 운동수행능력을 측정하였다. 그 결과 씨름선수들의 산소기여율은 운동시작 20초를 기점으로 유산소기여율이 급격하게 증가하는 것으로 나타났으며 이러한 증가시점(시간)을 본 연구에서는 산소기여율 역치수준으로 설정하였다. 또한 역치수준이전과 기존의 30초 윙게이트 운동평가간의 차이를 알아보기 위하여 20초까지의 운동수행능력과 기존의 30초 운동수행능력간의 상관분석을 실시하였으며 그 결과는 다음과 같다. 첫째, 씨름선수들의 윙게이트 운동 중 산소기여율은 20초이후 급격하게 증가하였다. 둘째, 윙게이트 결과 중 20초까지의 평균 회전수, 평균파워(KPM/sec, KPM/sec/kg), 피로지수(%)가 30초 윙게이트 결과보다 유의하게 높았으며 총일량(KPM/kg)은 30초 윙게이트가 더 높았다(p<.05). 셋째, 측정시간별 요인 중 인체효율성은 20초 피로지수와 유의한 부적 상관성이 있었다(p<.05). 이상으로 본 연구를 통해 씨름선수의 30초 윙게이트 검사 중 20초까지의 무산소성 운동수행 결과를 통해 씨름선수의 낮은 산소기여율(10%미만)에 의한 순수 무산소적 운동수행능력에 대한 평가가 가능할 것으로 생각되며 또한 20초까지의 피로지수를 통해 신체효율성에 대한 평가가 가능할 수도 있을 것으로 생각된다. 이러한 윙게이트 검사시간의 설정은 씨름선수라는 특정운동선수에 한하며 차후 다양한 운동종목간의 비교연구를 통해 운동종목별 특성을 발현할 수 있는 무산소성 운동수행능력의 평가시간에 대한 연구가 필요할 것으로 생각된다.
Abstract
The purpose of the present investigation was to suggest new variables of wingate test for Ssirum athletes based on the aerobic contribution during supramaximal anaerobic exercise. For the purpose, 12 Ssirum athletes of I university participated who had no injury or discomfort for maximal cycling exercise. we observed the change of aerobic contribution per 5 second during 30 seconds then we set up 20's point of whole period as "aerobic contribution threshold". With this threshold, we compared anaerobic capacity until 20's with 30's and the results were as following; the aerobic contribution during wingate test increased rapidly at 20 second. ② Mean RPM, mean power(KPM/sec, KPM/sec/kg), fatigue index(%) of 20's were higher than 30's significantly, but total work(KPM/kg) of 30's was higher(p<.05). ③ fatigue index of 20's had negative correlation with body efficacy(p<.05), but 30's had no relation. We concluded that anaerobic capacity until 20's during 30's wingate test might make the anaerobic capacity valuation with the low aerobic contribution and with fatigue index of 20's we might evaluate the individual body efficacy respectively of Ssirum athletes.
